I would liket to convet a time (gmt) to another time zone.

2004-03-16T14:01:00 to EST

The following snipplet does nothing, just puts "Central Europe Standard Time EST" after the time without converting it

set tS "2004-03-16T14:01:00"
[clock format [$tS getValue] -format "%Y-%m-%dT%H:%M:%S%Z EST"]

This works not also
set nT "14:01 EST"
[clock format [clock scan $nT -gmt yes] -format "%Y-%m-%dT%H:%M:%S"]

What is wrong with them?

I am still trying, but I would appreciate any help!

Best regards,
